boto.exception.NoAuthHandlerFound

[sdarwin]

Ubuntu 22.04, Python 3.10

According to the README you can create a file ~/.boto with credentials.

I have done that, using exactly that format.

However it consistently results in this error:

boto.exception.NoAuthHandlerFound: No handler was ready to authenticate. 1 handlers were checked. ['HmacAuthV4Handler'] Check your credentials

The full text is below.

What does work successfully is

export AWS_ACCESS_KEY_ID=
export AWS_SECRET_ACCESS_KEY=

So it's possible to continue using environment variables.

./bees up -k mykey

Just found a solution. Upgrade boto to 2.49.0. However requirements.txt is set to boto==2.38.0
